, Be it knownthat I, WALTER SCOTT, a citizen' ofthe United States Aof America, and a resident of Plainfield, county of Union, and

State of NewlJersey, have invented certain newfandv useful Improvements in Printin Machines, lof which the following is a speci cation.l a y My invention relates generally top rinting or 'othermachines and has, more particular reference to bed motions for av cylinder and bed-printing machine. t v

The object'pf the invention is to simplify the structure as'much as possible at the vsame time obtaininga high efficiency.y 'Broadly speakingth'e said invention lcons'ists'i'n the features of construction and combinations ofy parts disclosed in lthe lmorey par# ti'cular description'which foll'owsl` "Intlle accompanying drawings I have emout, however, restricting myself, tok the exact structure' shown.

` In the Said drawingsjrigurei is a Side e1@- vation of a machine embodying my invention'.

The improvement resides in the means raising yand lowering the ydriving shaft and gear,so as to, cause the latter. to engageaiternately the on thebed and for operating'the said ldriving shaft and gear, `V

modification which the weight of the driving-shaft and the members carried by the same is taken advantage of to cause the roll 31 to bear against the cam-surface 32, while the spring 33 is further utilized to keep the said roll snugly in position against the said inner surface of the cam. The difference between this construction and the one shown in Fig. l is simply that in thelatter the roll 15 bears against the outer surface of the cam 16 rather than against the inner surface of the same. Of course a spring similar to 33 can also be used in this construction, if desired.

What I claim is- 1. In a printing or other machine, the combination with an upper and a lower rack and a gear adapted to alternately engage with the same, of means for periodically lowering and raising the said gear comprising a pivoted bracket having bearings at its free end, a shaft on which the said gear is mounted supported in the said bearings, an arm carried by the said bracket composed of two parts bolted together at one point, a slot and corresponding bolt on the said two parts at another point, extensions on one of said parts projecting over the other of the said parts, and'set-screws passing through the said projections and bearing against the said other part, a roll carried at the end of said arm, and a cam with which the said roll engages.

2. In a printing or other machine, the combination with an upper and a lower rack and a gear adapted to alternately engage with the same, of means for periodically lowering and raising the said gear comprising a pivoted bracket having bearings at its free end, a shaft on which the said gear is mounted supported in the said bearings, means for rocking the said bracket, a stationary hub surrounding one of the bearings of the bracket, a

' gear mounted on the said hub, and means for transferring the motion from the said gear on the hub to the shaft carried by the bracket.

` 3. In a printing or other machine, the combination with an upper and a lower rack and a gear adapted to alternately engage with the same, of means for periodically lowering and raising the said gear comprising a pivoted bracket having bearings at its free end, a shaft on which the said gear is mounted supported in the said bearings, means for rocking the said bracket, a stationary hub surrounding one of the bearings of the said bracket having an axial hole somewhat larger than the diameter of the said bearing, a gear mounted on the said hub, and means for transferring the motion from the said gear to the shaft carried by the bracket.
